"The ED has filed prosecution complaint against Qureshi under the PMLA (Prevention of Money Laundering Act). He is in judicial custody," an ED official said.

The ED's move comes a day after it filed a chargesheet against Qureshi in the case in a Central Bureau of Investigation (CBI) court here.

Qureshi, arrested on August 25, was accused of dealing in 'hawala' money for government officials, including some CBI officers.

The ED had said that during its probe, facts emerged on acts of omission and commission of certain public servants holding high positions in collusion with Qureshi.

The agency said that records from the Income Tax Department revealed that Qureshi took a large amount of money from different people in lieu of "undue favours from public servants".

Various incriminating documents revealed that Qureshi, through his company India Premier Services Pvt Ltd (IPSPL), applied for obtaining concessionaire agreement from the Airport Operating company DIAL (Delhi International Airport Limited) for running lounge services at Terminal 3 of the Indira Gandhi International Airport in Delhi, an ED statement said.

"Some BlackBerry Messenger (BBM) messages indicate that certain government servants were in close touch with Qureshi and some other government servants dealing with the case were providing confidential information to him about various details."

In order to secure security clearance, other public servants not connected with the case were influencing officers concerned to accord permission, the ED statement said, adding some conversations indicate money changed hands.

"However, the permission was not granted due to reservation of intelligence agencies."
